There are a few points to consider here. Think about how you want to use the new space, which direction it faces and the size of investment you’d like to make. If you love having the space flooded with natural light then solar control glazing has developed in recent years and will help keep an ambient temperature.
A solid roof will give your space more of an extension feel, and you can include glazed panels or Velux windows if you’d like the best of both worlds.
